Hi all I have an x86_64 kernel running with i386 userland rootfs. Long back I believe there were some fixes for btrfs-tools which ran smoothly in this setup but after several dist-upgrades and long forgotten command, the btrfs-tools commands have started to fail
for instance $ sudo btrfs fi sync . ERROR: sync ioctl failed on '.': Inappropriate ioctl for device $ Is there any fix for this ?
